fix: iac test result undefined

snyk iac test scan would fail when trying to access snykIacTestScanResult?.scanAnalytics.supressedResults, in the case of snykIacTestScanResult being undefined.
This is because the whole snykIacTestScanResult?.scanAnalytics would evaluate to undefine and suppressedResults would fail to read an undefined value.
Added a "?" operator to scanAnalytics to fix this error.
